How to use Facebook without giving away all of your data

OK, so the recent Cambridge Analytica – Facebook scandal has ruffled the Internet's collective feathers. Once again, we are reminded that we live in an era where it's a bit too easy to overshare. If you are still fuzzy on what all the data has been used for — political consultants use the information gathered to target different types of people with different types of ads. Based on the data, the politician is advised on where they should hold a speech, what to say, how to “brand” themselves.

iPhone Permission Settings

On your iPhone, open the Settings app and scroll down until you find Facebook. If you have ever given Facebook the permission to look for your Location, use your Camera, or Microphone — this is where you can disable those permissions. If you want to tag yourself for being at a bar — you can do so manually, by looking for the place within the app. If you want to upload or send a photo — take it with your dedicated Camera app, then send it within the Facebook app. Easy as that, no need to grant those permissions if you are feeling paranoid about them.

If you have Messenger, WhatsApp, and Instagram installed, you can do the same for them. Same rules apply.

Android Permission Settings

Go into Settings → Apps → Facebook → Permissions. You can disable Location here. Now, a lot of speculation is going around that Facebook may or may not be using your phone's microphone to listen for keywords that may help with ad targeting. We won't go as far as to comment whether these are true or false, but if you are worried about this, go ahead and disable access to Microphone and Camera. From here on out, whenever you want to share a clip or photo, don't take it with the Facebook app. Instead, go into your Camera, take your photo, go back to Facebook and share them manually.

If you have Messenger installed, and you most probably do — do the same with its permissions. Same goes for Instagram and WhatsApp. You can easily share videos and pictures that you've already taken with your Camera through those apps — no reason to give them access to your phone's resources.

Facebook Privacy Settings

Now, open up the Facebook app and access the sandwich menu, which is the rightmost tab. Scroll down to Account Settings → Privacy. In “Manage Your Profile”, you will be able to manage your profile data — the city you live in, where you went to school, your workplace, phone number, family and relatives. You know, if you delete these now, there's no guarantee they will actually be wiped from the Internet forever. But at least take a mental note of what you've shared and what you'd like to not share in the future.

Back in Privacy, the “Limit who can see past posts” option is also a great “nuke it all” option if you suddenly feel remorseful about sharing too many posts with a setting of Public or Friends of Friends. Basically, it will instantly switch all your posts that you've ever made to the “Friends” setting. This means that anyone who is marked as “acquaintance” or anyone who is not your friend at all will not be able to see them, unless they are tagged in them.

Go back to the Account Settings sub-menu and enter Location for a brief moment. Since we removed the Location permission from the phone's settings, you will be warned that the toggles in this menu won't work unless you grant that permission back. That's OK, we're not here to do that. Get rid of the prompt and turn off “Location History”.



Now, let's get to the interesting bit. Go back to Account Settings and down to the Apps sub-menu. Here's a breakdown of what you can do in each tab:



1. Logged in with Facebook — this will give you a list of all the apps, polls, games, and services you've ever synced to your Facebook. Guess what, even if you uninstall the app, the service itself still has permission to access your profile. So, scan through them carefully and delete any one you no longer use.

2. Platform — this is the “nuke it all” option for the above tab. If you want to stop the Facebook platform from interacting with any website, any app, and any service you ever visit, enable this. This means that, from now on, you will have to use alternative methods to log in other apps, if such are available.

3. Apps others use — the main issue with the Cambridge Analytica scandal was not only that they siphoned profiles of people that were taking an online quiz, but also managed to collect all of the data on those people's friends lists. In fact, many apps will do this — they will ask for access to your friends list and then collect names, pictures, bios, posts, current city, activities and so on. Enter this menu and turn off everything.

4. Old versions of Facebook for mobile — this menu should only concern you if you have an ancient smartphone with a really old Facebook. Back in the day, you couldn't choose which groups of people should be able to view your posts. This option here lets you lock in a default setting for a post's audience, in case you still use an old BlackBerry from time to time.

Once more, go back to Account Settings and enter the Ads sub-menu.

This is another interesting one — here, you will see what Facebook knows about your (potential) interests and let you remove them. Now, we wouldn't say this is exactly The Devil right here — if a person loves dogs and technology, we're pretty sure that they'd be delighted to get an ad about a new app that helps you train dogs, right? But, for the sake of privacy and awareness, take a good look at those menus and choose what you want to remove:

1. Your Interests — this lists the categories that Facebook thinks you like. Tap “See all your interests” if you want to delete some or all of them

2. Advertisers you've interacted with — this is an important sub-menu. It will not only show you which advertisers' ads you've clicked on, but also which one of them actually have your contact info.

3. Ad Settings — pretty basic, this is where you choose whether or not the data that Facebook has on you can be used to target you with ads that are more relevant to you.

4. Hide Ad Topics — this sub-menu can be used if you're tired of seeing ads for specific categories like games, pets, et cetera. You can disable Ad Topics for 6 months, 12 months, or forever.

Posting tips

Now that we've gone through the settings and permissions, it's time to have a real talk about what we are actually posting, liking, and sharing.

OK, Facebook is a social media and we obviously want to use it to get in touch with our social circles. So “Don't post at all!” is a pretty counter-intuitive tip. But really, do you need to tag yourself in every business you visit? Remember, we disabled location settings, but if you make a post saying “Down in Papa John's y'all!” and tag yourself you are kind of inviting

the Facebook algorithm to go "Hey, this guy likes pizza!".

And, of course, a crazy selfie shared among friends can do no harm. You may want to pay careful attention to your audience settings for every post — cycle through "Public" and "Friends" regularly. “But Facebook analyzes photos and now it knows how I look!”. Yeah, so does Google and Apple. Our point is — if you want to keep your mugshots out of digital farms, be really, really careful which cloud services you upload to. And do know that whatever you've uploaded thus far is there forever.



Whenever you like an article, that's recorded. Whenever you share it — Facebook remembers. So, remember that your Facebook profile is just an online avatar of yourself. And we advise you to sculpt and structure that avatar in a specific way — make it a character that is detached from you but still has your interests. For example, if you are interested in smartphones — by all means like, visit, and converse in smartphone-oriented pages. The ads you see will be relevant to your interests and everything that corporations will be able to learn about you from your profile is going to be “Yeah... this is Joe. He likes phones.”

On the other hand, sharing your family tree, doing a photo-dump of the last birthday party or wedding you attended, getting into every political or religious discussion, filling out your profile data to the T... those things might be a bit too much.
